Fret Zealot - the best guitar accessory for helping you master the guitar. It’s an LED accessory that lights up your fretboard finger locations in any color. With a Fret Zealot installed on your guitar, this companion app lets you learn quickly and intuitively without the constant distraction of looking at books, videos, or sheet music to find out where to put your fingers.

The Fret Zealot App connects to your fretboard wirelessly via Bluetooth. You can concentrate on technique and finding your style right from the start as Fret Zealot lights the way.
The app contains a Tuner, Chords, Notes, Scales, and an expanding set of songs, all of which can be displayed directly on your guitar’s Fretboard. Lessons coming soon!

Incredible potential that has not yet been met


Obligatory disclaimer: I initially left a rather frustrated review of this app below. Due to the developers thoughtful and complete response, I’ve updated this with my current thoughts below.

As a beginner at guitar, I can say one thing about the Fret Zealot as a whole; after playing around with it for a single night, I know it’s going to change my life.

In my previous review, I complained about several aspects of the FZ app that I found to be less than what I was expecting in terms of functionality, intuitiveness, and aesthetic appeal. The developers responded to virtually all of my concerns, which you can read below.

I have faith that what they’ve communicated is true and that the app will be continually updated over the next several months. If that happens, I think that this may end up being the most paradigm-shifting guitar learning tool ever made, especially for all of us visually-oriented learners out there who have struggled to grasp the mysteries of the fretboard for what feels like ages.

I mean it. If you’re serious about learning guitar in 2018, you need to look into this thing. There are rough edges, including some manufacturing issues on the hardware side of things on this initial run, but if properly developed and supported, I can see the FZ ecosystem becoming synonymous with guitar in several years from now.

Keep it up, guys.

Seamless integration between the app and product


I’m a newbie at guitar, and just looking around the app, I can already tell I’m going to be able to learn so much faster than I have in the past. I’ve actually gotten to play on a Fret Zealot, and the connection between the app and product are seamless - you can play along to your favorite songs. They’re continuing to build the song library - can’t wait to see what shows up next!

Amazing app for amazing product


Very clean app that works seamlessly with the product. I love everything these developers make
